416.1 General. 2 psi gas piping systems designed in accordance with this section
and other requirements of this code are intended for use where the building
service regulator has been set to deliver gas at 2 psi. Piping systems shall
be designed to allow a maximum pressure drop of one and one half (1½)
psi between the meter and the regulator that reduces the pressure to seven (7)
inch w.c. Piping systems shall be further designed to allow up to one (1) inch
w.c. pressure drop between the above first cut regulator and the appliance or
the appliance regulator if used.

416.2 Gas Piping
Materials. All piping shall be metallic material only, and comply with 403.
Piping installed for 2 psi pressure shall be (1) type L copper tubing, (2) refrigeration
service tubing having a wall thickness of not less than .030", (3) corrugated
stainless steel conduit, (4) iron pipe. All piping and tubing shall be sized
so as to not exceed the capacities shown on tables 1003A, 1003B, or 1003C. Iron
pipe already in service may be retained. Aluminum tubing will not be installed
or used for this service. All horizontal tubing shall be supported at approximately
four (4) foot intervals.
416.3 Marking. All piping in the 2 psi portion of the system shall be marked
at the beginning, all ends with a metal tag stating "2 psi." All such
tubing or piping must also be marked at intervals not to exceed six (6) feet
with approved means of identification designating 2 psi gas pressure.
416.4 Piping in Partitions. When copper tubing is installed in a hollow partition
in a new piping installation, a metallic sleeve, or equivalent means, shall
be used to protect the tubing where it passes through a wood plate or other
structural member of the wall. The sleeve, if used, shall extend at least four
(4) inches on either side of the structural member in the partition. Iron pipe
may be used for the sleeve. The ends must be reamed to avoid sharp edges which
may come in contact with copper tubing. Tubing in the partition shall have some
slack. Concealed tubing joints are prohibited.
416.5 General Piping. All fuel lines from the meter shall pass through the foundation
with iron pipe, then a pipe to flare adapter may be installed for the copper
tubing. In such case that the piping system cannot pass through the foundation,
iron pipe will run from the meter to the outside wall of structure and attach
with suitable pipe straps then adapt to copper tubing. Installation procedures
must guard against dirt, tubing cutting chips, or other material entering the
fuel line. Blow out lines before connecting and testing.
416.6 Joints and Fittings, Tubing. All joints and fittings in 2 psi tubing shall
be made with standard SAE heavy duty short shoulder flare fittings having a
forty-five (45) degree flare. All joints and fittings in 2 psi corrugated stainless
steel conduit shall be made with approved fitting design for that system. Brazed
or silver soldered joints made with an alloy having a melting temperature in
excess of 1000 degrees fahrenheit are permitted. Soft solder joints are not
permitted.
All joints in existing copper tubing must be inspected and tested before being
used for 2 psi service. All soft solder joints will be replaced with a flare
fitting or with a silver solder joint. All bends should be smooth without any
binds in tubing. Bending springs or tubing benders should be used.

416.7 MP Regulators.
MP pressure regulators installed in the 2 psi portions of the piping shall comply
with the following provisions:
416.7.1 The MP regulator shall comply with Sections 402.1 and 402.13 and shall
be stated by its manufacturer as being suitable for the inlet and outlet gas
pressures for which it is to be used.
416.7.2. The MP regulator shall maintain a reduced outlet pressure under lock-up
(no flow) conditions and shall be so installed on the piping system that they
cannot be concealed by building construction.
416.7.3. The capacity of the MP regulator, determined by published ratings of
its manufacturer, shall be adequate to supply the appliances served by it.
416.7.4. The MP pressure regulator shall be accessible for servicing and may
be located either indoors or outdoors. When located indoors, the regulator shall
be vented to outdoors or equipped with a vent limiting device, in either case
complying with Section 410.3.
416.7.5. The service regulator shall be set to deliver 2 psi, with flow of 30
CFH, after which the adjusting cap shall be sealed with a copper wire and lead
seal. The regulator will be marked with a red cap and a metal tag stating 2
psi attached. The gas meter will be installed with a Red index indicating 2
psi system.

416.8 The regulator
which reduces the pressure from 2 psi to seven (7) inch w.c. shall be located
as close as practical to the appliance which it serves. This regulator must
be installed where it cannot be concealed by building construction. The 2 psi
to seven (7) inch w.c. regulator must be vented to the outside atmosphere or
must be equipped with a vent limiter device. When installed for one appliance
only, the preferred location of the regulator and its shut off cock is above
the floor level and immediately adjacent to the appliance it serves.
416.9 Appliance regulators, when used, may be installed on or adjacent to the
appliance manifold. Appliance regulators are not required on manually operated
room heaters, ranges or similar appliances not equipped with a pilot. A pipe
nipple at least six (6) inches long, or equivalent tubing, must be installed
between the 2 psi to seven (7) inch w.c. regulator and the appliance regulator.
Existing appliance regulator shall be retained on any appliance, unless defective.
416.10 Manual Shutoff Valve. Where there is more than one MP regulator in the
complete piping system served by one meter, a listed shutoff valve shall be
installed immediately ahead of each MP regulator. A listed shutoff valve shall
be installed ahead of each 2 psi to seven (7) inch w.c. regulator. Individual
runs of tubing may be made to each appliance from a manifold. The cocks may
be at the manifold, but they must be easily accessible, and identified as to
the appliance served.

or more shall be provided with venting systems or other approved means for removing
the vent gases to the outside atmosphere so the aggregate input rating of the
remaining unvented equipment does not exceed the 20 Btu per hour per cubic foot
figure. When the room or space in which the equipment is installed is directly
connected to another room or space by a doorway, archway, or other opening of
comparable size which cannot be closed, the volume of such adjacent room or

E:

Appendix E Suggested
Method for Checking for Leakage.

E1. Use of Lights.
Artificial illumination used in connection with a search for gas leakage shall
be restricted to battery-operated flashlights (preferably of the safety type)
or approved safety lamps. In searching for leaks, electric switches should not
be operated. If electric lights are already turned on, they should not be turned
off.
E1.1 Checking for Leakage Using the Gas Meter. Immediately prior to the test
it should be determined that the meter is in operating condition and has not
been bypassed.
Checking for leakage can be done by carefully watching the test dial of the
meter to determine whether gas is passing through the meter. To assist in observing
any movement of the test hand, wet a small piece of paper and paste its edge
directly over the center line of the hand as soon as the gas is turned on. This
observation should be made with the test hand on the upstroke. The following
table can be used for determining length of observation time.

In case careful
observation of the test hand for a sufficient length of time reveals no movement,
the piping shall be purged and a small gas burner turned on and lighted and
the hand of the test dial again observed. If the dial hand moves (as it should),
it will show that the meter is operating properly. If the test hand does not
move or register flow of gas through the meter to the small burner, the meter
is defective and the gas should be shut off and the serving gas supplier notified.”
